Eternal Material Technology starts to construct its 15-ton OLED material plant, updates on its OLED material and TASF project

China-based Eternal Material Technology (EMT) announced that it has started to construct its 15-tons OLED material production facility in Hefei. Yesterday the company held a groundbreaking ceremony at the construction site. EMT company expects the plant to begin mass producing materials in the second half of 2021. The planned total investment of the project (which will also include production of other materials) is 500 million yuan (or around $72 million USD).

EMT says that it has been able to achieve design wins for its ETL materials, and also other OLED related materials - and has already achieved sales of over 230 million Yuan ($33 million USD). EMT offers over 20 different OLED materials.

Kyulux updates on its latest Hyperfluorescence TADF emitter performance

Kyulux presented a new paper at SID Displayweek, that shows the latest progress of the company's Hyperfluorescence OLED emitter platform. You can see the latest performance chart below.

Kyulux TADF HF material specifications, August 2020

Hyperfluorescence combines TADF and fluorescence emitters, which enables high-efficiency (~100% IQE) emitters that feature long lifetimes and a very narrow emission spectrum. The company's yellow HF emitter is already commercialized, and now Kyulux says that its red and green materials are "close to commercialization". The company is also improving the color point and lifetime of its HF blue emitters.

Noctiluca continues to improve its TADF emitter platform

This is a sponsored post by Noctiluca

Poland-based TADF developer Noctiluca reports that the company continues to improve its emitter platform, and the company recently concluded testing a new family of emitters that have revealed great TADF properties, good to excellent QY and blue emission. Noctiluca released the raw data (available from company under the NDA) that details the performance of several new blue emitters. Here is a link to the summary of these results.

TADF emitter comparison - Noctiluca and commercial emitters

Noctiluca’s Team have a history of making custom high purity compounds to specific needs, and its TADF compound family has a high level of customization which will allow the company to tailor its materials for specific OLED stacks. In fact the company's next step is to work with industry leaders and OLED material developers to test its materials within commercial-grade OLED stack architectures to continue its development work and enhance the performance of its OLED emitters.

The UK awards $2.6 million towards an efficient deep blue OLED emitter research project

A consortium of researchers from three different Universities int he UK (Durham University, Newcastle University and Glasgow University) was awarded with £2 million ($2.6 million USD) towards a new project to develop new OLED emitters.

The new project aims to develop an "ultra-efficient" deep-blue OLED emitters. It is not clear whether this is a more efficient fluorescent-type emitter, or a next-generation material design.

Korean researchers develop a highly-efficient deep-blue phosphorescent OLED emitter

Researchers from Korea's Pusan National University have developed an efficient deep-blue phosphorescent OLED emitter. The researcher say that their new materials has an EQE of 24% while the color point is CIE (0.149, 0.085).

According to the Korean press, the main achievement in this research was the adjustment of the doping concentration of a novel dopant (mer ‐Ir1) to optimize the balance of electron and holes in the light emitting layer.

A Q&A with Cynora's CEO, to discuss the company's new blue emitter

OLED material developer Cynora recently announced its first commercial product, the cyBlueBooster fluorescent blue emitter that is 15% more efficient that current fluorescent blue emitters on the market.

This was a very interesting announcement, and Cynora's CEO Adam Kablanian was kind enough to answer a few questions we had to help understand the new material and Cynora's current business and latest technology.

Cynora announces a new blue fluorescent emitter that is 15% more efficient than current emitters

OLED material developer Cynora announced its first commercial product, a fluorescent blue emitter that is based on an "advanced molecular design" that is 15% more efficient that current fluorescent blue emitters on the market. Cynora brands its new material as cyBlueBooster, and it says it is currently available for commercialization in several shades of blue.

This could be very exciting news - while the whole industry is looking for next-generation emitters using TADF or PHOLED technologies, Cynora could have found an easier path to reduce power consumption by 15%. OF course a TADF or PHOLED emitter will achieve a reduction of 75% in power consumption compared to currently-used fluorescent emitters.

TCL and Juhua Printing showcase an inkjet-printed 31" FHD rollable hybrid QD-OLED TV prototype

Update: It seems we were mistaken, this prototype is not a hybrid QD-OLED, but a 'regular' OLED. This is still an impressive development - a rollable inkjet-printed OLED display.

TCL and Juhua Printing demonstrated a 31" FHD inkjet-printed rollable hybrid QD-OLED TV prototype. The display uses an IGZO (Oxide-TFT) backplane and TCL says that it has an aperture ratio of over 50%, brightness of 200 nits and a 90% DCI-P3 color gamut.

TCL's hybrid display technology (which TCL calls H-QLED) uses a blue OLED emitter coupled with red and green QD emitters. All three emitter materials are combined and printed using ink-jet printing technology.

TADF OLED emitter technology - industry status

TADF, or Thermally Activated Delayed Fluorescence, is a relatively new class of OLED emitter materials that promise efficient and long-lifetime performance without any heavy metals. TADF research started at around 2012, originally at Kyushu University in Japan and today many academic groups and several commercial companies are developing TADF materials.

Blue TADF emitter molecules

The main reason companies are interested in TADF emission is that it could lead to an efficient and long-lasting blue OLED emitter - something that hasn't been yet achieved by other means (mainly - UDC's Phosphorescent OLED emitter technology). In recent years companies initiated commercial development of red, green and yellow TADF emitters as these can offer a lower cost alternative to UDC's PHOLEDs materials.

Early-stage startup Noctiluca to commercialize new TADF OLED compounds

A new company has recently been launched in Poland, to commercialize a new family of TADF OLED compounds. Noctiluca, which takes its name from a bio-luminescent marine creature, was established a few months ago with aims to be the world's first company to produce a commercial-ready blue TADF emitter.

Noctiluca's story begins with an innovative organic DSSC solar cell platform that was developed at Synthex, an organic chemistry development platform company based in Toruń, Poland. A few years ago the researchers turned their attention to light emitting materials (which are quite similar to the light harvesting materials used in solar panels) and intensive research culminated in a promising family of new TADF compounds - which was then spun-off as Noctiluca,
